T2 / Are the other options affected if I customize the tune?

[m7alfayez]

Hello,
I’m sorry my first language not English and I have a question.

I got custom tune, and my car is little bit Rich and I need to lean it few. When I go to the customization option I see the options set as 0 input, it seems the tuner he didn’t do anything. So, If I modified the WOT and I saved the tune. The device also will saved the other options as 0 which my tunes settings will be cleared because all the options set as 0.

Thank you.

you will not see the changes made by the custom tune in the user defined parameters.

Thank you Mikel, so if I made one change on the custom tune it will overwrite and touch the entire the tune? Or just what I changed. The parameters with 0 input the device after save my changed will read it as 0? like stock tune
